PROBLEM TO BE SOLVED: To provide a capacitor unit which gives consideration to wiring of a bus bar for connecting capacitors with each other in addition to heat countermeasures and compactness.SOLUTION: First to third capacitor elements (first to third elements) of a capacitor unit 10 each have a rectangular parallelepiped shape with electrodes on both ends thereof. The second and third elements are arranged in a case 12 in a manner such that positive electrodes thereof face each other. The first element is arranged in the case in a manner such that negative electrodes thereof face side surfaces of the first and second elements. A bolt 18 couples a bus bar extending from the positive electrode of the second element and a bus bar extending from the positive electrode of the third element, a bolt 17 couples a bus bar extending from the negative electrode of the first element and a bus bar extending from the negative electrode of the second element, and a bolt 19 couples another bus bar extending from the negative electrode of the first element and a bus bar extending from the negative electrode of the third element. The bolt 18, the bolt 17, and the bolt 19 are arranged between the first element, and the second and third elements. |
